NVSL Diagnostic Virology Laboratory


Diagnostic Virology Laboratory (DVL) performs diagnostic testing for numerous domestic and foreign animal viral diseases, such as vesicular stomatitis (VS), highly pathogenic avian influenza (HPAI), virulent Newcastle disease, Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE), Venezuelan equine encephalomyelitis (VEE), equine infectious anemia (EIA), bluetongue (BT), swine influenza, pseudorabies (PR), and West Nile encephalitis. Providing diagnostic testing for these diseases and other viral agents is part of DVL's role in protecting the American livestock industry.

The DVL is a Reference Laboratory for the World Organization for Animal Health (OIE) and a Reference Centre for the Food and Agriculture Organization of the United Nation (FAO).
